Texas, April 21- Average retail gasoline prices in Texas have risen 1.5 cents per gallon in the past week, averaging $3.48/g yesterday, according to GasBuddy's daily survey of 13,114 gas outlets in Texas. This compares with the national average that has increased 2.3 cents per gallon in the last week to $3.62/g, according to gasoline price website GasBuddy.com.

Including the change in gas prices in Texas during the past week, prices yesterday were 14.0 cents per gallon higher than the same day one year ago and are 14.4 cents per gallon higher than a month ago. The national average has increased 11.9 cents per gallon during the last month and stands 12.1 cents per gallon higher than this day one year ago.

"The national average now stands at its highest level since last August," said GasBuddy.com Senior Petroleum Analyst Patrick DeHaan. "The advance in prices has continued, with the worst jumps in areas of California, and southern states, where prices have increased anywhere from 15 to 30 cents per gallon in some cases. The increases will likely continue to persist, at worst for another month or so, but at best, we could see some relief arrive as soon as May rolls in," DeHaan said.
